Core Advantages
- Precise Dimensions: Manufactured by high-precision slitting equipment, the thickness tolerance is controlled within ±0.02mm and width tolerance within ±0.1mm, ensuring consistency in batch processing.
- Excellent Processability: It can be easily subjected to bending, stamping, welding, and surface treatment (anodizing, powder coating), adapting to diverse manufacturing needs.
- Lightweight & High Strength: With a density of 2.7g/cm³, it is lighter than steel while providing sufficient strength (especially heat-treatable 6000 series), reducing product weight.
- Strong Corrosion Resistance: The natural oxide film on the surface and alloying elements (magnesium, manganese) enhance corrosion resistance, suitable for indoor and outdoor applications.
- Cost-Effective: The slitting process has high material utilization rate, and the stable performance reduces post-processing costs, making it ideal for mass production.
Major Application Fields
- Electronics Industry: Used as heat sink strips for LED lights, conductor strips for transformers, and battery connecting strips, leveraging its good thermal and electrical conductivity.
- Construction Industry: Applied in architectural decorative strips, door and window frames, and ceiling edge strips, benefiting from its corrosion resistance and aesthetic appeal after surface treatment.
- Automotive Industry: Utilized for automotive trim strips, heat shield strips, and structural reinforcement strips, contributing to vehicle lightweighting and corrosion resistance.
- Packaging Industry: Used as can body strips, bottle cap sealing strips, and packaging box edge strips, due to its formability and food safety (for food packaging).
- Industrial Hardware: Manufactured into fastener strips, spring strips, and tool parts, relying on its balanced strength and ductility.
Quality Control & Storage
- Quality Indicators: Dimensional accuracy (tested by calipers and width gauges), surface quality (no scratches, burrs, or oxidation), and mechanical properties (batch sampling for tensile and elongation tests).
- Storage Guidelines: Store in a dry, well-ventilated warehouse to prevent oxidation; place on flat supports to avoid bending; separate different alloys and tempers to prevent confusion; cover with dustproof cloth to avoid contamination.
